To me, The Roommate, which comes out on Friday, looks like an update of Single White Female, a movie that I will never watch again. Living with roomies is hard enough as it is; it's not as if we need a creepy thriller to freak us out even more. Whether you live with roommates or your significant other, there are plenty of lessons to learn from my many years of living in weird neighborhoods and with sometimes-terrible roommates. Check out my tips, and hopefully you won't go through the same mistakes that I have!
